HINGE.

Application filed December 15,1924, Serial No. 755,863.

This invention relates to hinges and particularly to what are known ascovered joint hinges wherein the separate butts ofthe hinge arefashioned from sheet metal; and

y the object of the invention is to provide a hinge of the classspecified, one of the butts of which is formed from a strip of sheetmetal, one end portion of said strip being fashioned to form ahook-shaped end portion and a knuckle within the hoek-shaped end portionwhereby said knuckle forms the pivot portion of said butt and thehookshaped portion thereof forming a hood for partially closing thepivot portion of the butt; a further object being to provide a hinge ofthe class described, one of the butts of which is fashioned from sheetmetal and the end portion thereof being curved and fashioned to form ahood having top and bottom walls, and a pintle bearing within saidhook-shaped end portion; a stillA further object of the invention beingto materially simplify the construction of a hinge of the class underconsideration whereby the v manufacturing costs are reduced and a strongand durable hinge produced; and with these and other objects in view,the invention consists in a hinge of the class specified and in theimproved method of producing the same hereafter more specifically setout in the specification and claims.

The invention is fully'disclosed in the following specihcation, of whichthe accoml panying drawing forms a part, in which the :1:5 separateparts of my improvement are designated by suitable reference charactersin each of the views, and in which:

Fig. 7 is a longitudinal sectional view through the separate but-ts ofthe hinge with part of the construction broken away; and

Fig. 8 is a plan view of the pivot ends of the separate butts of a hingeshowing a slight modification in the formation of one f the hinge butts.

My invention relates to the construction of what are known as coveredlioint hinges and particularly to the construction of hinges of thisclass of two sheet metal hinge butts, and more particularly Vto theconstruction of the hinge but-t provided with theA means for covering orpartially covering the joint ofthe hinge.

In carrying my invention into effect, I provide a blank in the formY ofa strip or sheet of metal 1() of predetermined dimensions and in'constructing the hinge from saidV blank, the corner portions at one endthereof are cut out as indicated in dot and dash lines at 11 in Fig. Qof the drawing, leaving at said end portion a projecting tongue member12 of less transverse dimensions than the vremainder of saidblank. Theend portion of the blank including the tongue member 12 is thenfashioned to form a curved end portion 13 and in this operation thetongue memberfl)J is brought into engagement with one face of the blank10 and the shoulders 1li formed by the cut out corner portions 11 arearranged at an angle to the blank 10 as clearly seen in Fig. 3 of thedrawing. p

The next step in the formation of the hinge buttconsists in arrangingthe curved end portion 18 into position to facilitate the fashioning ofsaid end portion into predetermined formation, which result may bcaccomplished by the angular positioning of the blank thus formedindicated in full and dotted lines in Fig. 4 of the drawing or bybending the blank in the manner shown in full lines only'in said figure.By means of suitable dies, the curved end portion 13 as well as thetongue member 12 is fashioned to form thereof a curved hood portion 15within which is a pintle bearing 16, the hinge being recessed at theopposite sides of the pintle bearing as shown at 17 to receive theknuckles or pintle bearings on the other part or butt of the hinge; theabove result Sii bein(r produced by dies which depress the shoulderportions 14- and curved end portion 123 of the blank when positionedsubstantially as shown in Fig. 1 to force the metal into position toform comparatively thin walls 18 at the opposite sides of the bearing 16which constitute part of the hood, said walls 18 gradually increasing indimensions or thickness in extending into the plate of the hinge butt asclearly illustrated at 19 in Fig. 6 of the drawing. It will beunderstood that in the above forming operation a shoulder 20 is formedupon the periphery of the bearing 16, and the surface of this i shoulderis in parallel relation to the free edges of the hood portion 15.

In the above operation of forming the hinge, a iiare of the metal asdiagrammatically illustrated at 21 will result and the flares will betrimmed off in the next or trimming operation on the hinge.

The next step in forming the hinge consists in shaping and sizing thesame which will include the rebending of the hinge from the full lineposition shown in Fig. a back' into the dotted line osition, after whichthe small aperture 22 iorrned within the bearing 16 in its making, isbored or reamed to suit the size of a predetermined pintle pin 23. Itwill also be understood that in the above described operation offashioning the side portion of the blank to form the recesses 17 at theopposite sides of the bearing 16 and in the general shaping of the saidf end portion of the blank, a rough pin may be inserted into theaperture 22 to prevent the collapsing of the tongue 12 which partiallyforms the bearing 16.

It is also preferred that the knuckles 2a of the other member or body 25of the hinge be fashioned to form shoulders 26 which will cooperate withthe shoulder 20 to form a stop for limiting the swinging movement of onebutt upon the other within predetermined degrees, it being understoodhowever that the shoulder 2O may strike upon the face of the butt 25 toserve as a stop, the shoulder 20 being positioned on the butt formedfrom the blank 10 to provide for a predetermined swing of the hingebutts.

It will be understood that with the construction shown in Figs. 1 to 7inclusive, that the knuckles or bearing 2-1- of the hinge butt 25 areexposed through the top and bottom faces of the hinge (note Fig. 1 ofthe drawing) the hood 15 extending around the knuckles 24 to partiallyclose the same and to form a covered joint hinge. However, in Fi 8 ofthe drawing I have shown a modification in which the top and bottomfaces of the knuckles 26 are closed by walls 26 formed integral with theblank 10 or integral with the curved end portion of said blank and oneof these walls is shown in said figure, and these walls are apertured asShown at 27 to receive the pintle pin 23, and the apertures 27 may openoutwardly through the walls 26 as indicated at 2S which facilitates thecutting of the apertures 27 which are angular particularly in one of thewalls 26 to receive the angular shank or portion of a pintle pin toprevent the rotation of said pin in the hinge butt formed from the blank10. It will be understood however, that I am not necessarily limited tothe specific formation of the apertures 27 herein set out, nor am Ilimited to the specific shape or form of the curved end or hood portionof the hinge butt, and the pintle bearing within said hood portion, andvarious changes in and modifications of the construction herein shownand described and the method herein set out may be made within the scope4of the appended claims without departing` from the spirit of myinvention or sacrificing its advantages.

It will be apparent that in the finish trimming, sizing and shaping ofthe hinge butt fashioned from the blank 10, the top and bottom faces ofthe pintle bearing 15 may be finished and brought to predeterminedspaced relation to receive the other butt of the hinge, and the recesses17 cleaned out if necessary to pro-vide the free action of the separatebutt members one upon another.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is l 1. A hinge butt fashioned from a sheetmetal blank, the pivot end portion of Which is curved or hook-shaped inform and provided centrally thereof with an enlarged stock or bodyforming the bearing for a pintle pin, and said curved end portion of thebutt at the opposite sides of the enlarged stock or body being fashionedinto comparatively thin walls gradually increasing in thickness as theyextend into the plate of the butt and forming recesses at the oppositesides of the pintle bearing.

2. A hinge butt composed of sheet metal and provided at one end portionthereof with a curved hood portion and an integral pintle bearingportion partially formed by said hood portion, at the opposite sides ofwhich and Within the hood portion are recesses to receive the pintlebearings of the other butt of a hinge, and said hood portion includingend wall members extending at right angles to the butt and of a shapesubstantially similar to the cross sectional form of said pintle bearingportion.

3. A sheet metal hinge butt of the class described, the pivot endportion of which is curved or hook-shaped in form and provided centrallywith an enlarged stock or body substantially cylindrical in form andforming the bearing for a pintle pin and the curved end portion of thebutt at the opposite sides of the enlarged stock or body extending atright angles to form end wall members corresponding substantially inform to the cross sectional form of said bearing, and forming betweenthe same and said bearing recesses to receive the pintle bearings of theother butt of the hinge.

il. ln a hinge. a pair of sheet metal hinge members fashioned to form atone end thereof interenaging knuckles, the knuckle end portion of one otsaid hinge members being fashioned to form a hood portion having anintegral pintle bearing centrally of and Within the hood portion andpartially formed by said hood portion, the hood portion of said hingemember extending atthe top and bottom edges thereof to form endwallsadapted to enclose pintle bearing portions only oi the other member ot'the hinge.

5. A hinge butt composed of sheet metal and provided at one end thereofwith a curved hood portion, a pintle bearing Within said hood portionand partially formed thereby and by an extension on said hood portion, ashoulder on said pintle bearing in line with the tree edge ot the hoodp0rtion and recesses at the opposite sides of said pintle bearingadapt-ed to receive the pintle bearings of the other butt of a hinge.

6. A hinge butt composed of sheet metal and provided at one end thereofWith a curved hood portion, a pintle bearing Within said hood portionand partially formed thereby and by an extension on saidv hood portion,a shoulder on said pintle bearing in line with the free edge of the hoodportion, recesses at the opposite sides of said pintle bearing adaptedto receive the pintle bearings of the other butt of a hinge, and saidhood portion extending at the top and bottom edges thereof to form endWalls adapted to enclose the pintle bearing-,portions only of the hinge.

In testimony that'I claim the foregoing as my invention 'I have signedmy name this 5th day of Dec., 1924.
